Expensive semiconductor laser diodes have no tolerance for fast voltage or current transients. To minimize the risk of damage, a standard JFET-clamp circuit shorts the laser when there is no supply ...

The receiver circuit includes an electromagnetic relay to assist the switching process of external electric loads such as floodlights, home alarm systems, etc. At the heart of the laser beam sender is ...

This circuit was designed to meet a medical application’s requirement to drive a laser diode with reasonable precision and a minimum of components and footprint (the device is now in clinical ...

You can get a red laser diode pretty cheap these days—as cheap ... use it for some kind of communication, and whipped up a circuit to test it out. To do the job, he designed a modulator circuit ...

In addition, power control for the laser diodes is performed by automatically adjusting the power source to save power and minimize heat dissipation. Contains various protection circuits such as laser ...
